Crossfire 3870x2's Power needed?

Bytor · Oct 17, 2008

I'm going to use a drive bay PSU, either the Thermaltake or FSP one to power these cards. I'm not sure how much power these cards draw, but want to have enough...

These will be going in my AMD Rig...

FSP 450 watt?

Thermaltake 650 watt?

Either one should do fine. FSP would be the one that I go for.

I wish I could find a review on the net for them and really want to know how long those PCI-e cables are on both.

Thanks

Can't agree with you more. As far as buying one, I think newtekie1 had a Thermaltake 250W for sale.

EDIT: Or was it 450w "??" All I know is he had one for sale not too long ago.

I got this one for my 3870 x 2.
Works great and cables are plenty long in my mid tower case.
$20.00 cheaper also.
